Bridge Assemblies

Deck Forming

Bridges that require concrete decks to be poured post precast erection will need to have forming onsite for casting.  Precast/Prestressed bridge girders can include blockouts, embedded inserts, embedded pipe for automated screed machines and other miscellanist items to help secure contractor provided formwork to girder.  Often (we coordinated with precaster) formwork can be installed prior to installation for exterior girders to allow faster construction.

Deck Forming

Tie Rod

Box beam and voided slab bridge spans use tie rod assemblies to fasten sets of girder together.  Tie rods can either be oriented perpendicular to girder edge or on an angle based on if the bridge is located in a curve.  Recesses located beam side faces allow access to complete tie rod connection assembly once rod has been extended through girder.

Rail Post

Rail post assemblies can be added to deck bulb tee girders.  Steel post assembly is cast into the deck bulb tee top flange with anchor bolts extending up.  Options for pouring the curb as a secondary pour at precast plant are available or curb can be cast onsite by contractor.
